In the furnace business since 1895, Lennox continues to deliver innovative furnaces integrated with the leading-edge technology that's kept them at the top of the heating game for over a century. The company features both gas and wall furnaces, helping to meet the needs of your environment, and quiet operation and energy-efficient designs make them a welcome addition in your home.

Energy-Efficient

Energy-efficient Lennox furnaces help you save money on heating costs. Variable-capacity furnaces adjust automatically to meet your precise temperature requirements, and models with Precise Comfort technology let you fine tune the fan speed, heat and airflow capacity in increments as low as 1 percent, providing you with even more control of your space.

Durable Construction

Lennox furnaces are made with longevity in mind, with high-quality parts from their stainless-steel casings to their smallest internal components. However, time and use can cause wear or damage that degrades the performance levels of your furnace.
